    • A transmission structure of toy fire engine including a casing in which a power source is disposed and connected to a driving shaft for rotating two cams disposed in the casing and two cams disposed outside the casing. The outer cams serve to drive two lateral slide members to slide and push two decorative members pivotally disposed on two sides of the casing to pivot outward. One of the inner cams via a support rod abuts against a linkage set to drive a scaling ladder to pivot upward from the casing or downward to the casing. When the scaling ladder is pivoted to an upright position, a movable doll is driven to climb up along the scaling ladder. The other of the inner cams pushes a pushing slide member to depress a pushing shaft of a rotary power wheel set, making the rotary power wheel set descend and touch the ground for driving the toy fire engine to running.
    • 一种玩具消防车的传动结构,包括壳体,其中设置电源并连接到用于旋转设置在壳体中的两个凸轮的驱动轴和设置在壳体外部的两个凸轮。 外凸轮用于驱动两个横向滑动构件以滑动并推动枢转地设置在壳体两侧的两个装饰构件以向外枢转。 通过支撑杆的一个内凸轮与联动装置抵接以驱动一个梯度梯从壳体向上枢转或向下枢转到壳体。 当缩放梯旋转到直立位置时,可移动的洋娃娃被驱动沿着梯子爬升。 内凸轮中的另一个推动推动滑动构件以按压旋转动力轮组的推动轴,使旋转动力轮组下降并接触地面以驱动玩具消防车运行。

    • A ratchet mechanism for telescope devices on toy vehicles comprises a manually drivable driving gearwheel rotatably positioned on a telescope base body, a rack on the telescopic arm, the rack engaging with the driving gearwheel, and a pawl of ratcheting engagement with a tooth gap of the driving gearwheel for the telescopic arm to be fixed in different positions of displacement on the telescopic base body. The pawl consists of elastically flexible plastics material so that on the one hand it ratchets over the teeth of the driving gearwheel upon actuation of the driving gearwheel for the extraction of the telescopic arm and that on the other hand it is elastically deformable upon actuation of the telescopic arm in the direction of retraction. The pawl then ratchets over the teeth of the driving gearwheel while releasing the telescopic arm in the latter's direction of retraction.
    • 用于玩具车上的望远镜装置的棘轮机构包括可旋转地定位在望远镜基体上的可手动驱动的驱动齿轮,伸缩臂上的齿条,与驱动齿轮啮合的齿条,以及与齿槽啮合的棘爪 将伸缩臂的驱动齿轮固定在可​​伸缩基体上的不同位移位置。 棘爪由弹性柔性塑料材料组成,因此一方面,在致动驱动齿轮以驱除伸缩臂时,该棘爪一方面在驱动齿轮的齿上棘齿,另一方面,当致动 伸缩臂在收缩方向。 然后,棘爪在驱动齿轮的齿上棘齿,同时沿着后退方向释放伸缩臂。
